I installed Linux ARM SL and it recognizes the RJ45 ethernet ports, but I cannot get it to recognize the internal port for the IO cards.

For me going to Project -> Project Settings -> Visualisation -> check "Visible" and then check both "Activate property handling ..." and "Activate implicit checks ..." solved the problem.

If the Professsional Developer Edition (which includes the Test Manager) is not supported by Schneider, then an option is to use the Open Source Unit test framework. See: https://forge.codesys.com/lib/counit/home/Home/

Dear Forum, For anyone interested we have solved this problem. Before we were using a KNX TP/IP interface, now we are using a KNX TP/IP router, and it works like a charm now.

I also ran into this, try using Coil<1> as the type in the FBD box. From what I understand, with VAR_GENERIC CONSTANT, the compiler creates separate data types for each different function block declaration.

seems to be an accident but there is a workaround in the Configfile: [CmpSocketCanDrv] AsyncSend=1 and will be solved with 4.22.0.0 Release

Post by rossanoparis on Upgrading CODESYS runtime from v4.7 to v4.9 using a bash script leads to lose the licences stored in the soft container

System information - Controller: KUNBUS RevPi CONNECT-S - OS: Linux buster 32bit 5.10.103-rt62-v7l #1 SMP PREEMPT_RT armv7l GNU/Linux - CODESYS v3.5 SP19 Patch 2 I'm facing a problem related to codesys licences using a procedure based on a bash script. Such bash script detect the presence of new .deb files and install them on system. My automation solution don't allow to be maintained by dedicated personal, thus even the CODESYS runtime SW must be installed using an "automatic" procedure instead of using the CODESYS tool. remark I've been using the following procedure since the runtime v4.5 without any issue. Before installing the new runtime packages, I need to copy the file CODESYSControl_User.cfg (here attached) because of new section which is necessary to add in order to allow some folders to be written by CODESYS runtime v4.9 Up to now, this has been unnecessary, this is the main difference between my previos bash file and the new one. remark If I skip this action, everythings goes fine, but my CODESYS application can't work as it needs to access some folders on controller's file system. Process - Before the procedure: the licenses are OK (see attached file lic-01.png) - After the procedure: the new CODESYS runtime version is correctly installed, but the software container with v1.19 and all licences disappear (see attached file lic-02.png) This is the synthetic content of bash script I'm using. # Stop runtime sudo service codesyscontrol stop sudo service codesysedge stop # Move the new CODESYSControl_User.cfg file # New configuraton with folders declared sudo mv -f CODESYSControl_User.cfg /etc # Install runtime package echo N | sudo apt-get install -y --allow-downgrades codesyscontrol_raspberry_4.9.0.0_armhf.deb # Install edge gateway package echo N | sudo apt-get install -y --allow-downgrades codesysedge_edgearmhf_4.9.0.0_armhf.deb # Reboot controller sudo reboot Thanks in advance

Hi, I am trying to get a basic safety application to download but I keep getting an "Invalid ERR Ack input" and "The Standard Inputs Size of zero is not allowed". I am simply using 2 safety inputs through an "AND" block to 2 safety outputs. Any help would be appreciated. Regards Trevor.

When trying to connect to a Github repository in the Git remotes windows of Codesys, the user can be the account username or the account email, while the password is the Github token. (I know this is an old topic, but I lost some time figuring it out from the guides.)

To search for an exact phrase, put it in quotes. Example: "getting started docs"
To exclude a word or phrase, put a dash in front of it. Example: docs -help
To search on specific fields, use these field names instead of a general text search. You can group with AND or OR.
